Apparatus and method for manufacturing battery cell

Abstract

The present disclosure relates to an apparatus and a method for manufacturing a battery cell, and more particularly, to an apparatus and a method for manufacturing a battery cell, wherein a pressing jig provided with a semi-elliptical pressing part presses the battery cell to remove air bubbles from the battery cell.

What is claimed is: 
     
       1. A method for manufacturing a battery cell by removing air bubbles of the battery cell, the method comprising:
 filling an electrolyte into the battery cell having an electrolyte filling path formed on one side or both sides thereof; 
 pressing with a pair of pressing jigs so that the air bubbles formed by the electrolyte filling are discharged to the outside through the electrolyte filling path, wherein pressure is applied sequentially from a central portion of the battery cell to first and second peripheral portions, the first and second peripheral portions being located on opposite sides of the battery cell; and 
 removing the electrolyte filling path and sealing the battery cell after the pressing. 
 
     
     
       2. The method of  claim 1 , wherein pressing with the pair of pressing jigs is performed for a predetermined time. 
     
     
       3. The method of  claim 1 , wherein pressing with the pair of pressing jigs further applies a predetermined amount of heat when pressing the battery cell. 
     
     
       4. A method for manufacturing a battery cell by removing air bubbles of the battery cell, the method comprising:
 discharging a gas generated through a formation process from inside the battery cell having a gas discharge path formed on one side or both sides thereof; 
 pressing with a pair of pressing jigs so that the air bubbles remaining on the inner surface of the battery cell is discharged to the outside of the battery cell, wherein pressure is applied sequentially from a central portion of the battery cell to first and second peripheral portions, the first and second peripheral portions being located on opposite sides of the battery cell; and 
 removing the gas discharge path and sealing the battery cell after pressing with the pair of pressing jigs is performed. 
 
     
     
       5. The method of  claim 4 , wherein pressing with the pair of pressing jigs is performed for a predetermined time. 
     
     
       6. The method of  claim 4 , wherein pressing with the pair of pressing jigs further applies a predetermined amount of heat when pressing the battery cell.
